These works are all accompanied by an audio track, providing a context to the work. Click on a thumbnail image to the right and choose an audio track from the menu beneath the enlarged image. There are two audio qualities to choose from: '256K' for broadband and '56K' for 'dialup' connections.

There are also audio tours supporting the thematic groupings of the individual works. These can be found at the start of each of the other listed themes above, as indicated by the numbered menu.
